Wanted: Vintage SSM2044 16-Pin DIP Analog Filter IC

Ghost Market is collecting verifiable leads for original-production SSM2044 four-pole voltage-controlled filter ICs from Solid State Micro Technology for Music. The target is the vintage 16-pin dual-in-line device, including correctly identified SSM2044P-marked parts where applicable. Traceable unused stock or working pulls are welcome. Packages must be intact, pins complete and markings readable. Please disclose desoldering, corrosion, broken leads or any uncertainty about origin. Modern SSI2144 or V2044 replacements, adapter boards and remarked parts are outside this particular search. Please provide close-up photographs of the top, underside and both rows of pins, including all manufacturer and date markings. Helpful leads include workshop inventories, documented donor synthesizers and specialist stock with provenance. If operation has been checked, describe the setup and results; a matching printed number alone does not establish authenticity. Ghost Market is requesting sourcing information in its own name. This notice carries no customer order, purchase budget, quantity commitment or payment promise. Reference photograph: Electric Druid, SSM2044 VCF, https://electricdruid.net/product/ssm2044-vcf/ . The pictured chip is an identification reference, not Ghost Market inventory. The photograph does not establish the authenticity of any part subsequently offered.
